The apparatus control method according to an embodiment of the present disclosure includes applying context information including at least one of environmental information collected through a sensor of the electronic device or a network, or usage information generated by the use of the electronic device to a machine learning based first learning model in response to a user input, and displaying, on a display, a first shortcut related to an application determined on the basis of a result of applying the context information to the first learning model and displaying, on the display, a second shortcut related to a preset application.

CROSS-REFERENCE TO RELATED APPLICATION

Pursuant to 35 U.S.C. § 119(a), this application claims the benefit of earlier filing date and right of priority to Korean Patent Application No. 10-2019-0108330, filed on Sep. 2, 2019, the contents of which are all hereby incorporated by reference herein in its entirety.

BACKGROUND 1. Technical Field

The present disclosure relates to an apparatus and control method for recommending an application or a function of an application, and more particularly, to an apparatus and control method for recommending an appropriate application or a function of an application based on a recognized situation of an electronic device user.

2. Description of Related Art

In home appliances, cars, etc. in addition to smartphones, environments that can connect to internet and install and use application through network are increasing.

Existing smartphones and other products provide a function that recommends applications to the user, but the prior art mainly recommends applications or functions recently used by a user without considering the user's situation or recommends applications or functions with a high frequency of use.

In addition, the conventional application function recommendation scheme is also presented to the user without any particular distinction between the recommended applications.

Related Art 1 discloses a technique for recommending a recommendation application according to a specific place that can be utilized at a specific place according to the place where the terminal is located but it is simply recommending an application that can be used in a specific place, instead of a user's situation.

In particular, when the proximity between the user location information and the specific place location information presented in Related Art 1 becomes larger than a predetermined value, the method of recommending an application related to the place location information, for example, a department store application located at the place, is a uniform method without considering the time information or traffic information of the user passing through the place, and thus there is a problem of recommending the same application when always approaching the place.

Related Art 2 discloses a method for recommending an application based on a keyword extracted from content displayed on a display area of an electronic device.

Related Art 2 provides a method of determining the display order of the recommended application based on the frequency of use of the application of the user or the number of executions of the application executed together with the application displayed in the display area within a predetermined time range, but this also has a limitation considering only the history executed in the electronic device.

In such a way, when only the history executed in the electronic device is considered instead of the user's situation, it is difficult to recommend an application suitable for the user's situation.

In particular, since Related Art 2 recommends an application based on a text-based keyword in a memo, Social Network Service (SNS), image, etc., there is a problem of recommending an application based on insufficient data.

DETAILED DESCRIPTION

Hereinafter, exemplary embodiments disclosed the present disclosure will be described in detail with reference to the accompanying drawings, and the same or similar components are denoted by the same reference numerals regardless of reference numerals, and repeated description thereof will be omitted. In the following description, the terms “module” and “unit” for referring to elements are assigned and used exchangeably in consideration of convenience of explanation, and thus, the terms per se do not necessarily have different meanings or functions. In addition, in the following description of the embodiments disclosed in this specification, the detailed description of related known technology will be omitted when it may obscure the subject matter of the embodiments according to the present disclosure. Further, the accompanying drawings are provided for more understanding of the embodiment disclosed in the present specification, but the technical spirit disclosed in the present disclosure is not limited by the accompanying drawings. It should be understood that all changes, equivalents, and alternatives included in the spirit and the technical scope of the present disclosure are included.

Although the terms first, second, third, and the like, may be used herein to describe various elements, components, regions, layers, and/or sections, these elements, components, regions, layers, and/or sections should not be limited by these terms. These terms are generally only used to distinguish one element from another.

When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected, or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present.

The artificial intelligence (AI) is one field of computer science and information technology that studies methods to make computers mimic intelligent human behaviors such as reasoning, learning, self-improving and the like.

In addition, the artificial intelligence does not exist on its own, but is rather directly or indirectly related to a number of other fields in computer science. In recent years, there have been numerous attempts to introduce an element of AI into various fields of information technology to solve problems in the respective fields.

Machine learning is an area of artificial intelligence that includes the field of study that gives computers the capability to learn without being explicitly programmed.

Specifically, the Machine Learning can be a technology for researching and constructing a system for learning, predicting, and improving its own performance based on empirical data and an algorithm for the same. The algorithms of the Machine Learning take a method of constructing a specific model in order to obtain the prediction or the determination based on the input data, rather than performing the strictly defined static program instructions.

The term ‘machine learning’ can be used interchangeably with the term ‘mechanical learning’.

Many Machine Learning algorithms have been developed on how to classify data in the Machine Learning. Representative examples of such machine learning algorithms for data classification include a decision tree, a Bayesian network, a support vector machine (SVM), an artificial neural network (ANN), and so forth.

Decision tree refers to an analysis method that uses a tree-like graph or model of decision rules to perform classification and prediction.

Bayesian network may include a model that represents the probabilistic relationship (conditional independence) among a set of variables. Bayesian network may be appropriate for data mining via unsupervised learning.

SVM may include a supervised learning model for pattern detection and data analysis, heavily used in classification and regression analysis.

ANN is a data processing system modelled after the mechanism of biological neurons and interneuron connections, in which a number of neurons, referred to as nodes or processing elements, are interconnected in layers.

ANNs are models used in machine learning and may include statistical learning algorithms conceived from biological neural networks (particularly of the brain in the central nervous system of an animal) in machine learning and cognitive science.

ANNs may refer generally to models that have artificial neurons (nodes) forming a network through synaptic interconnections, and acquires problem-solving capability as the strengths of synaptic interconnections are adjusted throughout training.

The terms ‘artificial neural network’ and ‘neural network’ may be used interchangeably herein.

An ANN may include a number of layers, each including a number of neurons. In addition, the Artificial Neural Network can include the synapse for connecting between neuron and neuron.

An ANN may be defined by the following three factors: (1) a connection pattern between neurons on different layers; (2) a learning process that updates synaptic weights; and (3) an activation function generating an output value from a weighted sum of inputs received from a lower layer.

ANNs include, but are not limited to, network models such as a deep neural network (DNN), a recurrent neural network (RNN), a bidirectional recurrent deep neural network (BRDNN), a multilayer perception (MLP), and a convolutional neural network (CNN).

In this specification, the term ‘layer’ can be used interchangeably with the term ‘level’.

An ANN may be classified as a single-layer neural network or a multi-layer neural network, based on the number of layers therein.

In general, a single-layer neural network may include an input layer and an output layer.

Further, in general, a multi-layer neural network may include an input layer, one or more hidden layers, and an output layer.

The Input layer is a layer that accepts external data, the number of neurons in the Input layer is equal to the number of input variables, and the Hidden layer is disposed between the Input layer and the Output layer and receives a signal from the Input layer to extract the characteristics to transfer it to the Output layer. The output layer receives a signal from the hidden layer and outputs an output value based on the received signal. Input signals between the neurons are summed together after being multiplied by corresponding connection strengths (synaptic weights), and if this sum exceeds a threshold value of a corresponding neuron, the neuron can be activated and output an output value obtained through an activation function.

In the meantime, a deep neural network with a plurality of hidden layers between the input layer and the output layer may be the most representative type of artificial neural network which enables deep learning, which is one machine learning technique.

On the other hand, the term ‘deep learning’ can be used interchangeably with the term ‘in-depth learning’.

The Artificial Neural Network can be trained by using training data. Here, the training may refer to the process of determining parameters of the artificial neural network by using the training data, to perform tasks such as classification, regression analysis, and clustering of inputted data. Such parameters of the artificial neural network may include synaptic weights and biases applied to neurons.

An artificial neural network trained using training data can classify or cluster inputted data according to a pattern within the inputted data.

Throughout the present specification, an artificial neural network trained using training data may be referred to as a trained model.

Hereinbelow, learning paradigms of an artificial neural network will be described in detail.

Learning paradigms, in which an artificial neural network operates, may be classified into supervised learning, unsupervised learning, semi-supervised learning, and reinforcement learning.

Supervised learning is a machine learning method that derives a single function from the training data.

Among the functions that may be thus derived, a function that outputs a continuous range of values may be referred to as a regressor, and a function that predicts and outputs the class of an input vector may be referred to as a classifier.

In supervised learning, an artificial neural network can be trained with training data that has been given a label.

Here, the label may refer to a target answer (or a result value) to be guessed by the artificial neural network when the training data is inputted to the artificial neural network.

Throughout the present specification, the target answer (or a result value) to be guessed by the artificial neural network when the training data is inputted may be referred to as a label or labeling data.

Throughout the present specification, assigning one or more labels to training data in order to train an artificial neural network may be referred to as labeling the training data with labeling data.

Training data and labels corresponding to the training data together may form a single training set, and as such, they may be inputted to an artificial neural network as a training set.

In the meantime, the training data may exhibit a number of features, and the training data being labeled with the labels may be interpreted as the features exhibited by the training data being labeled with the labels. In this case, the training data may represent a feature of an input object as a vector.

Using training data and labeling data together, the artificial neural network may derive a correlation function between the training data and the labeling data. Then, through evaluation of the function derived from the artificial neural network, a parameter of the artificial neural network may be determined (optimized).

Unsupervised learning is a machine learning method that learns from training data that has not been given a label.

More specifically, unsupervised learning may be a training scheme that trains an artificial neural network to discover a pattern within given training data and perform classification by using the discovered pattern, rather than by using a correlation between given training data and labels corresponding to the given training data.

Examples of unsupervised learning include, but are not limited to, clustering and independent component analysis.

In this specification, the term ‘grouping’ can be used interchangeably with the term ‘clustering’.

Examples of artificial neural networks using unsupervised learning include, but are not limited to, a generative adversarial network (GAN) and an autoencoder (AE).

GAN is a machine learning method in which two different artificial intelligences, a generator and a discriminator, improve performance through competing with each other.

The generator may be a model generating new data that generates new data based on true data.

The discriminator may be a model recognizing patterns in data that determines whether inputted data is from the true data or from the new data generated by the generator.

Furthermore, the generator may receive and learn from data that has failed to fool the discriminator, while the discriminator may receive and learn from data that has succeeded in fooling the discriminator. Accordingly, the generator may evolve so as to fool the discriminator as effectively as possible, while the discriminator evolves so as to distinguish, as effectively as possible, between the true data and the data generated by the generator.

An auto-encoder (AE) is a neural network which aims to reconstruct its input as output.

More specifically, AE may include an input layer, at least one hidden layer, and an output layer.

Since the number of nodes in the hidden layer is smaller than the number of nodes in the input layer, the dimensionality of data is reduced, thus leading to data compression or encoding.

Furthermore, the data outputted from the hidden layer may be inputted to the output layer. Given that the number of nodes in the output layer is greater than the number of nodes in the hidden layer, the dimensionality of the data increases, thus leading to data decompression or decoding.

Furthermore, in the AE, the inputted data is represented as hidden layer data as interneuron connection strengths are adjusted through training. The fact that when representing information, the hidden layer is able to reconstruct the inputted data as output by using fewer neurons than the input layer may indicate that the hidden layer has discovered a hidden pattern in the inputted data and is using the discovered hidden pattern to represent the information.

Semi-supervised learning is machine learning method that makes use of both labeled training data and unlabeled training data.

One semi-supervised learning technique involves reasoning the label of unlabeled training data, and then using this reasoned label for learning. This technique may be used advantageously when the cost associated with the labeling process is high.

Reinforcement learning may be based on a theory that given the condition under which a reinforcement learning agent can determine what action to choose at each time instance, the agent can find an optimal path to a solution solely based on experience without reference to data.

Reinforcement learning may be performed mainly through a Markov decision process (MDP).

Markov decision process consists of four stages: first, an agent is given a condition containing information required for performing a next action; second, how the agent behaves in the condition is defined; third, which actions the agent should choose to get rewards and which actions to choose to get penalties are defined; and fourth, the agent iterates until future reward is maximized, thereby deriving an optimal policy.

An artificial neural network is characterized by features of its model, the features including an activation function, a loss function or cost function, a learning algorithm, an optimization algorithm, and so forth. Also, the hyperparameters are set before learning, and model parameters can be set through learning to specify the architecture of the artificial neural network.

For instance, the structure of an artificial neural network may be determined by a number of factors, including the number of hidden layers, the number of hidden nodes included in each hidden layer, input feature vectors, target feature vectors, and so forth.

Hyperparameters may include various parameters which need to be initially set for learning, much like the initial values of model parameters. Also, the model parameters may include various parameters sought to be determined through learning.

For instance, the hyperparameters may include initial values of weights and biases between nodes, mini-batch size, iteration number, learning rate, and so forth. Furthermore, the model parameters may include a weight between nodes, a bias between nodes, and so forth.

Loss function may be used as an index (reference) in determining an optimal model parameter during the learning process of an artificial neural network. Learning in the artificial neural network involves a process of adjusting model parameters so as to reduce the loss function, and the purpose of learning may be to determine the model parameters that minimize the loss function.

Loss functions typically use means squared error (MSE) or cross entropy error (CEE), but the present disclosure is not limited thereto.

Cross-entropy error may be used when a true label is one-hot encoded. One-hot encoding may include an encoding method in which among given neurons, only those corresponding to a target answer are given 1 as a true label value, while those neurons that do not correspond to the target answer are given 0 as a true label value.

In machine learning or deep learning, learning optimization algorithms may be deployed to minimize a cost function, and examples of such learning optimization algorithms include gradient descent (GD), stochastic gradient descent (SGD), momentum, Nesterov accelerate gradient (NAG), Adagrad, AdaDelta, RMSProp, Adam, and Nadam.

GD includes a method that adjusts model parameters in a direction that decreases the output of a cost function by using a current slope of the cost function.

The direction in which the model parameters are to be adjusted may be referred to as a step direction, and a size by which the model parameters are to be adjusted may be referred to as a step size.

Here, the step size may mean a learning rate.

GD obtains a slope of the cost function through use of partial differential equations, using each of model parameters, and updates the model parameters by adjusting the model parameters by a learning rate in the direction of the slope.

SGD may include a method that separates the training dataset into mini batches, and by performing gradient descent for each of these mini batches, increases the frequency of gradient descent.

Adagrad, AdaDelta and RMSProp may include methods that increase optimization accuracy in SGD by adjusting the step size, and may also include methods that increase optimization accuracy in SGD by adjusting the momentum and step direction. In SGD, momentum and NAG are techniques that increase the optimization accuracy by adjusting the step direction. Adam may include a method that combines momentum and RMSProp and increases optimization accuracy in SGD by adjusting the step size and step direction. Nadam may include a method that combines NAG and RMSProp and increases optimization accuracy by adjusting the step size and step direction.

Learning rate and accuracy of an artificial neural network rely not only on the structure and learning optimization algorithms of the artificial neural network but also on the hyperparameters thereof. Therefore, in order to obtain a good learning model, it is important to choose a proper structure and learning algorithms for the artificial neural network, but also to choose proper hyperparameters.

In general, the artificial neural network is first trained by experimentally setting hyperparameters to various values, and based on the results of training, the hyperparameters can be set to optimal values that provide a stable learning rate and accuracy.

In this case, after the usage information of boarding 612 the subway at a certain range of time from 8:00 a.m., which is the user's commute time, is stored, when receiving input for activating the application recommendation function from the user, the electronic devices 100 a and 100 b may recommend a reading application to the user based on a result of recommending the reading application from the learning model to which the environmental information and the usage information are applied.

For another example, even if the same user boards 622 the bus at a certain time from 8:00 a.m. and after usage information, which is workplace information storing the movement direction of a bus or information on a path different from a commuting path each morning, is stored, when receiving input from the user to activate the application recommendation function, the electronic devices 100 a and 100 b may recommend the traffic information application to the user based on a result of recommending the traffic information application from the learning model to which the environmental information and the usage information are applied.

In the same manner, when the context information 610 different from the context information 620 that is repeatedly recorded every day is inputted to the learning model, the results of the learning model and the recommended application may vary.

Referring to FIG. 7 , recommended applications or functions of applications may be different according to different users.

For example, the learning model may be trained with environmental information and usage information in which user A 710 executes a content application, an internet browser application, and a reading application mainly at home. In this case, when receiving an input for activating the application recommendation function from the user located at home at a certain range of time from 10 am 712, which is the user's wake-up time, the electronic devices 100 a and 100 b may recommend a reading application to the user based on a result of recommending the reading application from the learning model to which the environmental information and the usage information are applied.

Referring to FIG. 8 , in one embodiment, the processor 550 may display, on the display 540, the plurality of first shortcuts 840 and the plurality of second shortcuts 830 in a circular form having a different curvature or a semicircular form having a different radius or different positions from a specific point of the display 540. Therefore, the user can intuitively recognize the shortcut of the preset application and the shortcut of the application recommended by the electronic devices 100 a and 100 b.

In one embodiment, when the number of the first shortcut 840 and the second shortcut 830 is large, the display 540 may display only some of them and display the remaining shortcuts when the user rotates the displayed area by touch.

Referring to FIGS. 9 to 12 , when the electronic device 100 a or 100 b receives an input for enabling the application recommendation function from the user while the user uses the specific application, a learning model and an interface that the electronic device 100 a or 100 b recommends an application or an application function to a user will be described.

In one embodiment, referring to FIGS. 10 to 12 , the preset second shortcut may be set identically to all running applications.

In another embodiment, the preset second shortcut may be set differently for each application executed by the user or by the electronic devices 100 a and 100 b. In this case, the second shortcut may be a shortcut for a function provided by the running application or a shortcut for a function provided by another application.

Steps performed in a method for recommending an application or a function of an application according to an embodiment of the present disclosure will be described with reference to FIGS. 13 and 14 . In the following description, description of parts that are the same as those in FIG. 1 to FIG. 12 will be omitted.

Referring to FIG. 13 , in step S1310, the electronic devices 100 a and 100 b may receive an input for activating a function for recommending an application from a user.

In step S1320, the electronic devices 100 a and 100 b may apply context information including at least one of environmental information collected through a sensor or a network and usage information generated by use of the electronic devices 100 a and 100 b to machine learning based learning models.

In one embodiment, the learning model may be a learning model received from the server devices 200 a and 200 b, or may be a learning model that is re-trained using the learning model received by the electronic devices 100 a and 100 b from the server devices 200 a and 200 b as training data in which an application or an application function which a user selected is configured as a label under the condition of specific context information.

In step S1330, the electronic devices 100 a and 100 b may display the first shortcut related to the application determined based on the result of applying the context information to the learning model.

For example, the recommended application may be derived as a result of the context information applied to the learning model, or the user's situation (e.g., a “working” situation) may be derived as a result of applying the learning model. In the latter case, the application or function of the application related to the derived situation may be recommended as the first shortcut.

The electronic devices 100 a and 100 b may display, on the display, a first shortcut and a second shortcut related to a preset application or a function of the application regardless of the application result of the context information to the learning model or context information.

In another embodiment, the electronic device 100 b may determine whether the electronic device 100 b is connected to another device before performing step S1310, and receive a user input for operating the application recommendation function in step S1310 from the connection devices 300 a and 300 b through the network connected to the connection devices 300 a and 300 b.

In this case, the electronic device 100 b controls or requests the other devices 300 a and 300 b to display the first shortcut and the second shortcut on the display of the other devices 300 a and 300 b connected to the electronic devices 100 a and 100 b.

In an embodiment, when it is determined that the electronic device 100 b is connected to the other devices 300 a and 300 b, the context information inputted to the learning model may include usage information related to types of other devices 300 a and 300 b (e.g., ‘vehicle’, ‘fridge’, etc.), and depending on the results of applying context information to the learning model, an application related to the other devices 300 a and 300 b (for example, a ‘navigation application’, a ‘music playing application’, etc.) may be recommended or “driving” situation may be derived.

In one embodiment, the electronic device 100 b may control or request other devices 300 a and 300 b to display only the shortcuts for the applications associated with the type of connected device 300 a, 300 b as the first shortcut among the recommended applications according to the results of applying the context information to the learning model.

After displaying the first shortcut and the second shortcut on the display, the electronic device 100 a or 100 b may monitor the user's reaction regarding whether the first shortcut is used, and store, as context information, steps associated with the response (e.g., steps of closing a shortcut display of the recommended application and executing another application).

In one embodiment, if the user runs another application without using the first shortcut recommended a preset number of times, run other applications without using all of the first shortcuts associated with the determined particular situation, or run other applications without using the first shortcut recommended within a particular time range and this lasts for a predetermined period of time, the electronic devices 100 a and 100 b may re-train the learning model. In the case of the learning model in which the electronic devices 100 a and 100 b re-train the learning model received from the server devices 200 a and 200 b, the training model can be re-trained with training data that reflects additional context information generated or stored after the training.

Steps of training the learning model received from the server device 200 a or 200 b by the electronic device 100 a or 100 b according to an embodiment of the present disclosure will be described with reference to FIG. 14 .

In step S1410, the electronic devices 100 a and 100 b may receive a learning model from the server devices 200 a and 200 b, and generate and store context information including at least one of environmental information or usage information for a predetermined period of time. In this case, at least one of environmental information or usage information may be stored in association with geographic information or time information. For example, if a user runs an SNS application, by relating classification, execution time, execution place, network connected at execution, moving speed at execution, illumination at execution, and the like to each other, it can be stored as context information.

In step S1440, the electronic devices 100 a and 100 b may train the learning model by using the training data that labels the learning model received from the server devices 200 a and 200 b with information running an application or a function of an application by a user of the electronic devices 100 a and 100 b under the conditions of various context information.

In one embodiment, before performing the step of training the training model received from the server devices 200 a and 200 b, the electronic devices 100 a and 100 b may determine whether the electronic devices 100 a and 100 b are connected to a power source (for example, a power source that can continue to supply power) in order to determine whether the power supply is smooth while training the learning model in step S1420.

In another embodiment, the electronic devices 100 a and 100 b may determine whether the user uses the electronic devices 100 a and 100 b in order to train the training model while the user is not using the electronic devices 100 a and 100 b.

In another embodiment, in step S1430, the electronic devices 100 a and 100 b estimate amount of time the user is expected not to us the electronic devices 100 a and 100 b (e.g., a time to sleep normally based on a usage pattern of the electronic devices 100 a and 100 b of the user), and compare the estimated amount of time the user is expected not to use the electronic device with the estimated amount of time for training the learning model to perform the training of the learning model only when the estimated amount of time to train the training model is smaller than the estimated amount of unused time the user is expected not to use the electronic device.

In an embodiment, the electronic device 100 a or 100 b may transmit to the server devices 200 a and 200 b the difference (e.g., differences in parameters or node structures such as thresholds, weighting values, etc.) between the learning model generated after the training model and the training model before training. Accordingly, the electronic devices 100 a and 100 b may train the learning model without transmitting personal information to the server devices 200 a and 200 b, and the server devices 200 a and 200 b also may improve the learning models held by the server devices 200 a and 200 b by using differences between the learning models received from the electronic devices 100 a and 100 b.

In an embodiment, the electronic device 100 a or 100 b may transmits the trained learning model to the server device 200 a or 200 b or another server device (not shown), and request to map the corresponding learning model to the user's information and store it. Therefore, even if the user uses multiple electronic devices or changes the electronic device, it is advantageous in receiving the stored learning model and using the application recommendation function. In addition, the server devices 200 a and 200 b may be to train the received learning model in the individual cloud server and provide a function for recommending an application based on the received context information each time the electronic device 100 a or 100 b makes a request. In this case, a function of recommending an application stably can be provided through the limited provision of personal information.
